Homewave stopped working with Yale Lock

I’m using the Homewave app on my iPhone 5 with a Vera Lite and Yale Keyfree lock. I have the latest update to Homewave and iOS 8.3.
Homewave would stop working off and on a few times per month over the last year. I could usually get it working again by unplugging and replugging the Veralite, but the last week it has completely stopped functioning even after restarting the Veralite and restarting the phone.
Homewave now says the lock is unlocked all the time and doesn’t control the lock anymore. I still get alerts when I restart the Veralite or if the the Veralite reboots on its own.
What can be done to fix this issue?

Do you see the same thing on the vera UI? if you do it is not a homewave problem. It could be that your lock is not communicating with the vera… In that case, did you add any devices that generates RF in the 900MHz frequency recently?
